Study Notes

BIOS Overview

Basic Input Output System (BIOS) acts as the "conductor" for computer startup, initializing hardware components and ensuring operational communication.
BIOS is stored in non-volatile memory on the motherboard, typically in the CMOS.

CMOS Details

CMOS (Complementary Metal-Oxide Semiconductor) stores configuration settings for BIOS and requires a battery to retain settings.
If the CMOS battery fails, the settings may show as incomplete, but the BIOS will still function; typical storage capacity ranges from 128 to 512 bytes.

BIOS Functions

Communicates with hardware components including RAM, hard drives, optical drives, and CPUs.
Monitors system conditions such as temperature, fan speeds, voltage, and clock/bus speed.
Provides diagnostic tools for memory, CPU, and drive tests; low-level formatting is not common with modern systems.

BIOS Firmware Updates

Firmware updates can resolve stability issues and improve overall performance.
Updates may fix boot issues when a computer fails to load an operating system.
Newer BIOS memory often utilizes flash memory, retaining data even when power is lost.

Risks and Protocols

Updating firmware poses risks like incomplete updates, which can render a computer non-functional.
BIOS updates are not part of routine maintenance and are performed for specific reasons.
Important steps for updating BIOS include checking the current version, backing up, reading documentation, ensuring a reliable power source, and closing all running programs.

Flashing the BIOS

Flashing refers to deleting old BIOS and rewriting new firmware using a "flash utility."

Additional Tools and Concepts

An Uninterruptible Power Supply (UPS) provides power during BIOS updates to prevent interruptions.
MSinfo32 is a system utility that provides comprehensive details about hardware, including BIOS specifications.
Virtual PC software like Microsoft Virtual PC or VMware Player can simulate BIOS interactions without affecting the actual system.

Unique BIOS Features

Features like USB port disabling, date and time settings, and hardware diagnostics are commonly found in BIOS. However, disk partitioning options are generally managed by the operating system.
Modifying BIOS configuration is often necessary for actions like disabling USB ports, which affects communication between components.
